Virgin Active charging deceased members accounts

For months on end Virgin Active has been overcharging my account , when you query with at home gym they direct you to the call centre . After calling the call centre and making multiple requests to cancel certain memberships including my deceased mums account they fail to accomplish this simple task . Each month I get charged exorbitant fees thats almost double my combined memberships. There is just no way at resolving this to date. If we are unable to sort this matter out with a matter of urgency after asking for 6 months through email, clubs , call centre then there is no option but to take this up with the complaints commision and in service of other consumers this matter will need to be widely circulated over Social Media.
